To all whom it may concern:

Be it known that l, WILLIAM ORR, a citizen of the United States, residing at Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in Metallic Lathing, fully de scribed and represented in the following specication and the accompanying drawings, forming a part of the same.

This invention relates t-o a means for supporting metallic lathing either ofthe charac` ter known as Wire-cloth or Wire-netting lathing or lathing made from sheet metal suit'- ably treated to provide for retaining the plaster thereon.

The means constituting the present invention is applicable both for the supporting of the lathing for ceilings or overhead work and for partitions or vertical Work generally.

In Vorder to convey a full understanding` of the invention, it will now be described in detail, reference being had to the accompany, ing drawings, which illustrate the application v of the invention in various forms both to overhead Work and to vertical Work, and in Which- Figure l is a sectional view showing the invention applied in one form to overhead Work. Figs. 2 and 3 are enlarged views of portions of Fig. 1. Figs. -LL and 5 illustrate modifications, which will be hereinafter referred to. Fig. G is an enlargedsection taken onthe line (5 of Fig. 1. Figs. 7 and 8 illustrate further modifications in overhead Work, which will be hereinafter referred to. Figs. 9 and 10 illustrate still other modifications. Fig. l1 illustrates another modification in overhead work, also one application of the invention to vertical or partition Work. Fig. 12 is a horizontal section taken on the line l2 of Fig. ll. Fig. 13 is a section taken on the line 13 of Fig. ll. Figs. 14, 15, and 16 illustrate other modifications, Which Will be hereinafter referred to. Fig. 17 is a section on the line 17 of Fig. 14.

Referring now particularly to Figs. 1 to S, it is to be understood that A represents the ordinary iron I-beams for supporting the ceiling of a room and the floor of the room above, B planks resting upon the tops of and eX- tending longitudinally of said beams, and C D oorin g planks and boards restin upon the planks B.

van57 of the ordinary forms.

E represents the metallic lathing to which the plaster is applied for the ceiling of the room, which lathing mavv consist of Wire cloth or netting', or may be Sheetmetal lathing of The beams A are placed at such distances from 'each other that it is necessar7 to provide supports for the lathing material between the beams in order to make the lathing sufficient-ly rigid to euable it to properly receive and support the plaster. For this purpose l provide a series of supporting-rods a, which extend from beam to beam and are located at such distances from each other lengthwise of the beams as to afford the proper support for the lathing. ln ordinary cases each of the rods o. is provided at one end with a hook 2, which hooks over the ange at the lower edge of one beam, and at its opposite end either with a similar hook 3, (see Fig. 4,) by which it is secured to the flange of the adjacent beam, or is threaded and provided with a nut-4, which engages with a clip 5, by which the rod is secured to the flange of the beam.

. If it is not desired to offsetthe rods a. from the beams A, the hooks 2 may be of the form shown at the left of Fig. 10, and the clips 5 of the form shown in Fig. 5 and at the right of Fig. lO. ln most cases, however, it will bc preferable to offset the rods d. more or less from the beams A, so as to provide spaces above the lathiug F. and beneath the beamsv to secure the proper locking of the plaster and an air-space. For this purpose there are provided offsetting-clips (i, of -the form best shown in Fig. 3, which are inserted between the beams and the hooks 3, and extending beneath the beams serve to maintain the rods at a short distance from the lower sides of the beams. To accomplish the same result at the opposite ends of the rods, the clips 5 are preferably formed as best shown in Fig. --that is to say, they are provided with openings through Which the rods a pass and with extensions which abut against the under sides of the beams, so as to offset the rods, the clips 5 thus constituting offsetting and attaching clips. The clips 5 G may extend the entire length of the beams A, or they maT be comparatively short, as indicated in Fig. G. In either case the clips and rods u. having IOO in Fig. 4.

been placed in position the rods will be secured firm-ly to the beams by tightening' the nuts 4 against the clips 5.

In those cases where it is desirable to dispense with the nuts 4 and the screw-threads upon the rods d the rods may be provided at the ends corresponding to their threaded ends with hooks 3, as shown in Fig. 4, between which and the clips 5 wedges 7 will be driven, so as to properly tighten the rods. In such case the shape of the oitsetting and attachingclips 5 will be slightly modified, so as to retain the wedges in position, as indicated It is evident that with a nut or wedge to draw the rods taut comparatively small ones can be made to support as much weight without deflection as the heavy and cumbersome angle-iron or channel bars heretofore used vfor this purpose, and that.

they can be much more easily and quickly applied.

The lathingl E may be secured to the rods a in any suitable manner. This may be accomplished by lacing the lathing at intervals to the rods, as indicated in Figs. 1 and G, or sheet-metal clips may be employed to fasten the lathing to the rods, or the lathing maybe `'formed with offset portions or loops at intervals, as indicated in Fig. 7, through which` the rods can be inserted so as to pass between -certain of the wires of the lathing, and in some cases the rods may be incorporated with the lathing in the process of weaving the same. In the case of sheet-metal lathing loops S may be struck up from the material of the lathing, through which the rods will be passed so as to secure the lathing thereto, as indicated in Figs. 14 and 17.

Where the plaster of a ceiling is quite thick and heavy or the spaces between the beams unusually wide, it may in some cases be necessary in order to prevent the rods ca from vsagging toV provide intermediate supports for said rods between the beams A. NVhere this is necessary, it can readily be accomplished in the manner shown in Figs. 1, 2, 4, 9, and 10. For this purpose there are provided supporting or stay rods b, which may be comparatively light rods. 'Ihese rods either pass under the rods a, about midway between the beams A, or are otherwise suitably secured thereto, and thence pass upward in opposite directions and over the tops of the beams A, being provided at their ends with hooks 9, (see Fig. 4,) by which they are secured to, the iianges of the beams. In passing above the beams A these rods of course pass through the planks B, which are provided with suitable openingstor the purpose, the planks'being secured in their position upon the tops of the beams by means of side clips 10, which lock under the iiangesof the beams.

In some-cases it maybe preferable to make the rods a in two or more parts, as indicated in Fig. 10, which parts are hooked together or otherwise connected at their meeting ends about midway ot` the beams A. The rods b may also be made in two parts, which are hooked or otherwise connected to the rods a, as also indicated in said figure. As indicated in Fig. 10, the rods 'a are not oitset from the beams A, but it is of course apparent that the rods a may be offset in this construction in the same manner as already described.

In some instances it may not be feasible to employ the clips 5 G or to provide the rods a with 'tightening-nuts, as already described, and in such cases the rods may be providedat their opposite ends with hooks. 12 of the form indicated in Fig. 9, which will engage with the adjacent flangesot the beams A, and in this case the rods a'will be 'sprung into position between the beams, so as to be maintained there bythe hooks 12. The hooks 12 may be formed so as to offset the lathing from the lower sides of the beams or the lath-` ing may rest against the lower sides ot' the 4prevent the lathing from yielding during the operation of applying the plaster, and this may be accomplished in the mannerindicated in Fig. 9, in which case the rods b are connected to eyes formed upon the rods a and are provided at their upper ends with nuts by which they are secured to clips 13, which tit over the upper sides of the beams A. By this means the rods b serve to support the rods d and the lathing in both directions.

In many cases it is desirable, in order to provide greater security against the spread of fire in a building, to provide a second coat or partition ot' plaster located between the plaster of the ceiling and the iioor of the -IOO Iroom above, and in such case it is also prefv erable to so locate the ceiling and the intermediate plaster as to provide an air-space between the two and also between the intermediate plaster and thelioo'r above. IVhere this is desired, it can readily be accomplished in the manner indicated in Figs. 1, 2, 3, and 7. For this purpose the upper sides of the beams A support a series of rods c, similar to the rods a and attached to the beam in a similar Inanner. In this case, however, the rods cneed not be offset from the beams, and are consequently connected at one end by a hook 2, similar to the hook 2 of Fig. 10, and at the other by a nut and clip 4 5, similar to the nut and clip of Figs. 5 and 10. The lathingv F is secured to the rods c in either of the ways before described.

In some cases it may be preferable to provide the intermediate partition of plaster in the form of arches extending between the beams, as indicatedin Fig. 7, and in this case the rods c can be sprung in between the beams so as to assume the arched form shown in said ligure, where they will be retained by their own elasticity without other fastening means. The lathing F may be placed either above or below the rods c, as preferred.

In forming arched ceilings the rods a and i their fastening-clips may be entirely omitted,

the plastered arches between the beams being supported by the rod c, as indicated in Fig. 7'. In this case the lathing will, of course, preferably be upon the under side of the rods c. Then the ceiling is formed in this manner, it will of course be desirable to provide coverings to conceal the-lower sides of the beams A and to protect them from the action of heat in case et fire, and for this purpose the lathing F will'be extended from one arch to another around the lower sides of the beams, as indicated in Fig. 8, it being supported by rods d, which extend around the lower sides of the beams and are connected vat their ends to the rods @by hooks or otherwise.

If it is desired to ottset the rods d from th lower sides of the beams, wedges 14 may be introduced between the beams and the rods, so as to hold the rods at aproper distance from the beams and at the same time properly 'tighten them.

In some cases it may be impracticable, owing to the location ot` the beams A, to employ the hooks and clips of the form which has been described for securing the rods d. There such conditions exist, the rods may be support-ed in the manner indicated inV Figs. 11

and 13, in which case the beams are provided.

with clips forretaining the rods, which are composed of hangers l5, located upon the opposite sides of the beams and engaging with their flanges, and connected together beneath the beams by tie-bolts 16, which pass through openings in the hangers and through tubular braces 17, located between the hangers to sustain them against the strain of the bolts. The portions of the hangers extending below the bolts 1G are provided with openin gs to receive the rods a, in which openings the rods may be held by nuts 4, screwed onto their threaded ends, as indicated in Figs. 11 and 13; or the lower ends of the hangers may form nuts having right and left th reads, into which the ends of the rods correspondingly thread ed are screwed.

TvVhat has been said in regard to overhead work also applies for the most part to' walls or partitions where the studding is composed et' beams of I or T form. The present invention may, however, be applied with good results to walls or partitions, or even ceilings made of solid masonry, or where wooden studding or beams are employed, In case of masonry walls or ceilings the rods d may be secured to metallic furringstrips f, which in this structure are the equivalent ot the flanges of the beams. The ends ot' the strips f may be embedded in the masonry, as indicated in Fig. 11, the strips projecting a sufficient distance from the walls to allow the rods to be secured by clips and hooks 2 5, the same as to the flanges of the beams, as alreadyT described; or the rods may be provided with clips 5 at each end, which clips form nuts, into which the rods are screwed by right and left screwthreads formed on their opposite ends, as indicated in Fig. 12. The furringfstrips j' will, in case ot a wall, preferably be arranged vertically, so that the rods d will extend horizontally; but this order may be reversed, and in some cases the furring-strips instead of being embedded in the masonry may be fastened to it otherwise, being properly braced to resist the strain of the rods a.

The furring -strips f insteadl of being of Ametal may be of wood, as indicated in Figs.

15 and 16, the edges of the strips being properly beveled to retain the hooks 2 and clips 5, this structure also being the equivalent of the flanges of the beams. y

The wooden strips f may be secured to the wall or ceiling in any suitable manner-as, for example, by nails or screws--and they may be properly braced to resist the strain of the rods a by cross-pieces g, introduced at proper intervals, as shown in Fig. 1.6.

This construction possesses the advantage of providing isolated dead-airspaces between the strips f and cross-pieces g, which will retard the spread of fire and afford protection against heat and cold. Cornices may be formed Where required, in the manner indicated in Fig. l1, by oblique rods h, having their upper ends attached to one of the hangers 15, or in any other suitable manner to the overhead beam or the rods a, their lower ends being embedded in the wall or partition or secured. thereto by nails or screws, as indicated. The lathing will be secured to the rods h in either of the ways already described.
